Kaitaku Inc. (Headquarters: Nakamachi 19-6, Shinjuku-ku, Tokyo / CEO: Tomonori Matsuki) has released "Supaden voice 2.0" (Female voice: Aoyama, Male voice: Shinagawa) equipped with a new dialogue model that realizes more accurate listening and natural responses for its telephone AI agent "Supaden", and will begin early access for a limited number of customers.
Release Background
Supaden has been supporting the telephone operations of many companies through the complete automation of inbound and outbound calls. As its adoption expands, there has been a continuous demand to utilize it in more advanced business areas:
- Handling more complex inquiries and multi-step business flows
- Further improving recognition accuracy for diverse customer speech patterns and contexts
- Adapting to detailed settings and scenarios required as business requirements become more granular
To meet these expectations, this new dialogue model has further improved accuracy in both speech recognition and response generation, strengthening its ability to handle complex business flows. It has reached a new standard in the essential quality criteria of telephone operations: "listen accurately and respond accurately."
New Dialogue Model: 3 Key Points
1. Further improvement in speech recognition accuracy: Supaden, which originally boasted Japan's highest level of recognition accuracy (over 98.7%), has further improved its listening accuracy. It can handle fast talking, abbreviations, and complex inquiries, preventing dialogue stagnation caused by repeated clarification and confirmation.
2. Stable support for complex business flows: It can now provide stable responses while maintaining response generation accuracy, even for inquiries spanning multiple steps, business scenarios involving conditional branching, and diverse customer speech patterns.
3. Support for more advanced business scenarios: It can now handle complex business flows that were previously abandoned due to setting constraints, as well as tasks requiring detailed response rules. The more complex the business requirements, the more you will feel the effect.
Main Use Cases
[Inbound Call Utilization]
In receiving inquiries and reservations from customers and business partners, the AI completes everything from accurate hearing to initial response. It can handle complicated inquiries and tasks requiring multi-stage confirmation, preventing the personalization of tasks while automating a wider range of telephone operations.
[Outbound Call Utilization]
In follow-up calls and confirmation contacts to dormant customers, it accurately grasps the recipient's response and completes a conversation that is viable as a business operation. Since everything up to CSV recording and CRM reflection of the results is automated, it becomes easier to run the PDCA cycle for outbound call operations.

"The strength of Supaden lies not just in taking calls, but in completing tasks. With this new dialogue model, it can listen more accurately and respond more appropriately. As the automation of telephone operations expands, we will broaden the range of advanced business areas that Supaden can handle. We will first provide it to limited customers and gradually roll it out to all users while confirming its quality in actual operation."
